IRLM dumps

IRLM uses the SDUMP system services of z/OS in the following situations:

• Within the IRLM address space
• While executing IRLM code or IMS code within the IMS address space
• While executing IRLM code for exits from SLM within the IMS address space

SDUMP dumps the IRLM address space to a SYS1.DUMPxx data set without formatting it. When dump processing completes, you can format the dump offline by specifying IRLM on the VERBEXIT subcommand in IPCS. If more than one IRLM is active in the system at the time the dump was taken, you must also specify the z/OS subsystem name (IRLMNM in the IRLM procedure). IRLM dump formatters that are shipped with a particular release of IRLM are specific to that release. If multiple IRLM releases are active, IPCS must be configured to have access to the appropriate IRLM PDS. The release of the IRLM in the dump must match the release of the IRLM in the IPCS STEPLIB.

To access z/OS component trace entries for IRLM, use the IPCS CTRACE or VERBX command. To see the syntax of the VERBX command for displaying traces, enter: IPCS VERBX IRLM 'help'.

Examples:

• If only one IRLM is in the dump, this command formats the IRLM address space:

  VERBX IRLM 'SUBsys=IRLM'
  or
  VERBX IRLM
  or
  VERBX IRLM 'SUB=IRLM'

• If more than one IRLM is in the dump, this command formats the KRLM address space:

  VERBX IRLM 'SUBsys=KRLM'
  or
  VERBX IRLM 'SUB=KRLM'

If you want to format dumps online during the abnormal termination process, you must change the FMTO parameter to request a SNAP dump.
